Shadow The Hedgehog, or also called "The Ultimate Life Form", is a black hedgehog with red lines and spiky hair. And Sonic's enemy.

After 20 years (again)(of saving the World with Sonic) Rouge The Bat (Shadow's best friend and Omega, a giant robot), thaws him from the capsule and at that moment Shadow comes out of the capsule coughing.

Shadow: "Holy shit... How long has it been?..."

Rouge: "Twenty years..."

Shadow: "SORRY, HOW MUCH?!"

He was surprised, standing up.
